Hi,
Is possible to use functions in conditional operator as ashown below.
.....
.....
int fun1()
{
// body
}
int fun2()
{
//body
}
....
main()
{...
int x;
x = (a>b)?fun1():fu n2();
} 30 2172

Yes,
it's semantically equivalent to:
if (a>b)
x = fun1();
else
x = fun2();
IMHO, I find that the conditional operator fits very well in this case.

Yes. And even more entertainingly, you can do this:
x = (a > b ? fun1 : fun2) (c, d, e);

Yes, of course! Never thought of stretching the meaning
of a function 'pointer' this far. Things like 5["Hello world"]
(as you know I'm sure) are entertaining too.

Are you saying that if functions 'fun1' and 'fun2' have the same
prototypes and take (appropriately typed) arguments, 'c', 'd', and 'e',
that this would be equivalent to:
if ( a > b )
x = fun1( c, d, e );
else
x = fun2( c, d, e );
?

BTW what other seemingly strange standard C construction
do you know? I mentioned 5["fsdssdfssf "] which looks
very strange to most people even very experienced C
programmers. It would be fun to discuss this kind of
constructs.

Yes. You can even use `x = (a > b ? fun1 : fun2)();'
if you have sado-masochistic tendencies.

About the whole human race of course. But I meant C

Not only that, you can even do
x=(a>b?fun1:fun 2)();
assuming that fun1 and fun2 are declared as functions.
(It is more interesting if they have arguments.)

It could happen. Take a look at this line of code
string = (digit == 0 ? sput_ip1 : sput_i)(integer / 10, string);
from http://groups.google.com/groups?selm...mindspring.com
sput_ip1 and sput_i, are functions.

Hi everyone,
Is there a reason why the Mid() function only works in one direction in
VBScript? This code works in VB6 but not in VBScript? Is there a way
around it? I am trying to create an ASP page which produces a fixed width
text file for import into a third party legacy application which I don't
have control over.

I am experimenting with function pointers. Unfortunately, my C book has
nothing on function pointers as function parameters. I want to pass a
pointer to ff() to f() with the result that f() prints the return value
of ff(). The code below seems to work, but I would appreciate your
comments. Have I got it right? Does the function name "decay" to a pointer?

Any comments on the correctness of the statements 1, 2a, 2b, 3 and 4 in
the code below?
If they are correct, then the definition of an object as well as that of
an lvalue is broken in C99 by the following reasoning:
foo() does not return an object, so the return of foo() conceptually is
not stored, yet we are able to obtain a pointer to one of its member
elements, therefore it must be stored, therefore foo() does return an
object,...

Consider this code (.Net 2.0) which uses a nullable type:
private void button1_Click(object sender, System.EventArgs e)
{
DateTime? nullableDate;
nullableDate = (condition) ? null : DateTime.Now;
}
When the condition is false, I want to return null. If true, I want to
return the current date/time.

I was just thinking that I understood the conditional operator when I coded
the following expecting it to fail:
int a= 10, b= 20, c= 0;
((a < b) ? a : b) = c; // a=0
a=20; b= 10;
((a < b) ? a : b) = c; //b=0
Now since the expresion 5 = c is not valid I did not expect the above to
work. But it does work. Why? I thought that the ?: operator would evaluate

Almost.
A function name *is* a pointer-to-function. You can do two things with it -
copy it (assign its value to an object of function pointer type, with a
cast if necessary but preferably to one of the /right/ function pointer

In hindsight, I am disappointed with the choice of conditional syntax. I know it's too late to change. The problem is
y = some thing or other if x else something_else
When scanning this my eye tends to see the first phrase and only later notice that it's conditioned on x (or maybe not notice at all!). Particularly if 'some thing or other' is long or complicated.
